serialization possibilities for a BaselineOf
by Dale Henrichs Oct. 13, 2015

Oct. 13, 2015

As an offshoot of the recent discussion with Steph and Christophe, I though it would be interesting to show folks what a BaselineOf specification would look like if it were written out in STON format. Here's a baseline spec extracted from the BaselineOfSton for GemStone in the GsDevKit/ston project[1]: spec for: #'common' do: [ spec package: 'STON-Core'; package: 'STON-UTF8-Core' with: [ spec requires: 'STON-Core' ]; package: 'STON-Tests' with: [ spec requires: 'STON-Core' ]; package: 'STON-UTF8-Tests' with: [ spec requires: 'STON-UTF8-Core' ]; yourself. spec group: 'default' with: #('Core' 'UTF8'); group: 'Core' with: #('STON-Core'); group: 'UTF8' with: #('STON-UTF8-Core'); group: 'Tests' with: #('STON-Tests' 'STON-UTF8-Tests'); yourself . spec package: 'STON-Core' with: [ spec includes: #('STON-GemStone-Core') ]; package: 'STON-GemStone-Core' with: [ spec requires: #('STON-Core') ]; package: 'STON-Tests' with: [ spec includes: #('STON-GemStone-Tests') ]; package: 'STON-GemStone-Tests' with: [ spec requires: #('STON-Tests') ]; yourself ] I spelunked around a bit in the Metacello project data structure and extracted this list using a simple workspace[2] to produce this STON output [ MetacelloPackageSpec { #name : 'STON-GemStone-Core', #requires : [ 'STON-Core' ] }, MetacelloGroupSpec { #name : 'UTF8', #includes : [ 'STON-UTF8-Core' ] }, MetacelloGroupSpec { #name : 'Tests', #includes : [ 'STON-Tests', 'STON-UTF8-Tests' ] }, MetacelloPackageSpec { #name : 'STON-UTF8-Core', #requires : [ 'STON-Core' ] }, MetacelloPackageSpec { #name : 'STON-Tests', #requires : [ 'STON-Core' ], #includes : [ 'STON-GemStone-Tests' ] }, MetacelloPackageSpec { #name : 'STON-Core', #includes : [ 'STON-GemStone-Core' ] }, MetacelloGroupSpec { #name : 'default', #includes : [ 'Core', 'UTF8' ] }, MetacelloGroupSpec { #name : 'Core', #includes : [ 'STON-Core' ] }, MetacelloPackageSpec { #name : 'STON-UTF8-Tests', #requires : [ 'STON-UTF8-Core' ] }, MetacelloPackageSpec { #name : 'STON-GemStone-Tests', #requires : [ 'STON-Tests' ] } ] The #for:do: specification is not present (that information was stripped during the version creation process), but that type of information could easily be added back in ... everything else is present and accounted for ...

[ANN] Cupboard inspector for Teapot
by Torsten Bergmann Oct. 13, 2015

Oct. 13, 2015

Hi, I took a few minutes to add a custom inspector tool ("Cupboard") to Teapot showing all the available teapots. The tool is accessible from the Tool menu right after loading "Teapot" and allows get an overview on running teapots. If you teapot has dynamic routes they will be shown as well. See screenshot attached. You can also start/stop a Teapot or add a new one serving static contents from a selected directory. Also catalog messages were added to the ConfigurationOfTeapot and the NeoJSON repo in the dependencies was fixed. Just get the lates stable version: Gofer it smalltalkhubUser: 'zeroflag' project: 'Teapot'; configuration; loadStable. or directly load from ConfigBrowser (Pharo 4) or CatalogBrowser/Spotter (Pharo 5) in a fresh image. If you want to quickly serve a (static) webpage from Pharo ========================================================== Create a web directory and HTML page - use "Tools" -> "File Browser" - create a directory "www" using "Add new directory", navigate to it - create a new file "index.html" using "Add new file", edit it and accept the changes Serve it from Pharo - load Teapot in a fresh image - open "Tools" -> "Teapot" - click on the server icon on the right to create a new static server - accept the default port 80 or enter a new one - select the directory Point your browser to http://localhost:80 If you want to quickly server (dynamic) content from Pharo: =========================================================== - use one of the examples on http://smalltalkhub.com/#!/~zeroflag/Teapot Note that the dynamic routes are shown in the new tool Tip: if you like use "Mustache" template library to mix HTML content (like Bootstrap templates, Material design templates or other with your Pharo server objects to serve pages) Have fun T.

Alien and FFI in Pharo
by Robert Withers Oct. 13, 2015

Oct. 13, 2015

I want to get NIO sockets working using FFI, which I understand means Alien. I can't seem to load Alien from the Catalog. What do you suggest I do? -- thanks, Robert

Slack?
by Yuriy Tymchuk Oct. 13, 2015

Oct. 13, 2015

Hi guys, Iâm thinking whether live chat can make sense for communication. And I know that there is IRC, but for some reason itâs not working for me (maybe because of clients). Iâve seen many teams using Slack [1]. Is anybody willing to try that out. Or also maybe some have already created a pharo team on Slack? Cheers. Uko [1]: https://slack.com/ <https://slack.com/>

Job | Seeking a Smalltalker for a PhD on Multi-Robot Systems
by Noury Bouraqadi Oct. 13, 2015

Oct. 13, 2015

Hi, My team has an opening for a PhD student to work on multi-robot exploration and mapping. We target search and rescue operations with UGVs controlled using PhaROS (Pharo + our client for the Robot Operating System). You'll find the full description below. More info on our team can be found at: http://car.mines-douai.fr <http://car.mines-douai.fr/> Best, Prof. Noury Bouraqadi Ecole des Mines de Douai Lille area France ------------ CONTACT Prof. Noury Bouraqadi, noury.bouraqadi AT mines-douai.fr <http://mines-douai.fr/> Dr. Luc Fabresse, luc.fabresse AT mines-douai.fr <http://mines-douai.fr/> Dr. Guillaume Lozengez, guillaume.lozengez AT mines-douai.fr <http://mines-douai.fr/> DESCRIPTION Robotic exploration and mapping is basic to many robotic applications and more specifically to search and rescue operations. It relies on robots to build a map of the environment as a first step to further mission specific tasks (eg. extracting trapped victims). In scenarios where time is critical such in the aftermath of an earthquake, the use of multiple robots allows to speed up the exploration and to take advantage of distributed sensor to increase the mapping process. Each robot explores a different but connected area. The global map is built by merging local maps built by individual robots. To build a map of an unknown environment, a robot has to perform Simultaneous Localization and Mapping (SLAM). Based on different perceived data (typically odometery and laser scans), metric SLAM algorithms localize the robot while building an occupancy grid. The occupancy grid models the environment as a matrix where each cell denotes the probability of occupancy of a small area. Best metric SLAM algorithms produce precise maps that allow localization with typically centimetric precision. However, an occupancy grid map is materialized as a large matrix. Beside the memory consumption, such a map leads to high CPU consumption for path planning. CPU consumption is also a concern in multi-robot exploration. Indeed, merging metric maps produced by different robots is computationally intensive. The above drawbacks of metrics maps can be mitigated by the use of topological maps. However, topological maps do not allow precise obstacle delimitations needed for autonomous robots exploration. The goal of this PhD is to contribute to our ongoing effort, and propose a solution that gathers the best of both worlds. The expected outcome is a SLAM algorithm that builds a topological map that embeds metric information. The target algorithm should be implemented on top of the ROS (www.ros.org <http://www.ros.org/>) middleware and validated both in simulation and on actual robots. It should also be supported by a set of automated tests that can safely run on an actual robot. BIBLIOGRAPHY - Robotic Mapping and Exploration. C. Stachniss.

updated Cryptography

I am attaching the .mcz as I am unsure where to publish it. I fixed a few issues (hex is lowercase and inputs to SecureRandom) and all tests pass green in the latest Pharo 5.0. Is there a good place for this to live? -- thanks, Robert
